New BBM Highlighted Pictures (Black Berry Messenger)

If you look throughout that link, you'll see that if you highlight the picture you can see it fully which in my opinion, is pretty cool.

The logos are made on transparent backgrounds with programs like photoshop, illustrator and fireworks or a mix of all of these. Some knowledge is required along with imagination and creativity to make these pictures. They look very simple but are not as easy as you might think.

Does anyone know how to do that? If so can you make me on saying "Disasterr" please?
